“We cannot fight free speech as ugly as it is sometimes with violence against people. Never justifiable. #garlandshooting #texasattack,” Linda Sarsour, the national advocacy director of the National Network for Arab American Communities, tweeted.

“People have the right to be racists & bigots. I have the right to call them racists & bigots. It ends there. #garlandshooting #texasattack,” she added.

Texas police shot dead two gunmen who reportedly opened fire on Sunday night outside an event organized by an anti-Islamic group to exhibit drawings of Prophet Mohammad (peace be upon him).

Sunday’s attack took place at about 7 pm in a parking lot of the Curtis Culwell Center, an indoor arena in Garland, northeast of Dallas.

“Talking about burning down mosques is cool it seems. Wonder if people would feel same if about other religious homes,” she added.

Other Americans, however, blame Geller for spreading hate in the first place.

“If you wanna hold an art show with art depicting Muhammad, go for it. It’s your right. But be ready when this shit happens. #PamGeller,” Zach Hamm tweeted.

Another, Glenn Greenwald, added: “Two of the key speakers/organizers of the “Draw Mohammed” event in Texas are Pam Geller and Geert Wilders.”

Geller, who has bragged online that she uses a Qur’an as a doorstop, was the subject of a CAIR “Islamophobe profile” documenting the individuals and organizations involved in spreading anti-Muslim bias in the United States.

CAIR also listed her as a member of the “inner core” of those promoting anti-Muslim bigotry.

Geller is known for her anti-Islam bus campaigns that were launched in several American states, amid widespread outrage.
